To all whom it may concern Be it known that I, STEPHEN R. \YABREN.

a citizen of the United Akron, in the county of of Ohio, fulImprovements in States, residing at Summit and State have inventedcertain new and use Pulley Thnnbles of which the following is aspecification.

This invention relates are used on constructions such as than air craftwhere the pulley is to pulleys which lighter in contact with a surfaceof the same.

One object of a unitary shield and pulley form. A second objectis orpulley my invention is to provide in a compact to provide a sheave in ahousing structure in such a manner that the point of application of theload is on the axis of the pulley.

Further objects will be more fully set forth in the annexedspecification and claim.

In the drawings Fig. 1 is a front elevation of my device,

half in section.

Fig. 2 is a side elevation.

Fig. 3 is a section on line 3?; of Fig. 1..

Referring to the drawings, 1 represents the body portion of the combinedpulley and thinible which is bifurcated to provide side pieces 2 and 3,between the wheel 4. The upper which is mounted part of the body 1sprovided with a groove 5 starting at the top of the same and extendingdown to form a thnnble or grommet for the supportwhich the ing rope orcable, groove and through passes around this hollow wheelsupportingshaft 6. This shaft is passed through the holes in the pulleyw heel and the sides 2 and 3 and is then peened over at 7 at S incontinuation of the groove Serial No. 616,611.

and filed out Thi s shaft rotatably supports the bushing i) which isforced into the pulley wheel -tl-.

Integrally formed on the side 3 of the ropes or cables.

adaptable for construction as in; with the side of the the sameat alltimes.

This device is particularly use in. lighter than air craft the chafingplate in contactballoon will protect The side continuations ll. 11, ofthe body portion of part 1 form a shield for the rope passing around thepulley wheel and at the same time serves to help maintain the devicewith the chafing.

plate l in of the construction it I claim fiat against the adjacentsurface is mounted upon.

In a combined pulley and cable thinible. a pulley wheel. a hollow shaftrotatablv mount ing the same,

a bifurcated support for said shaft. one leg,- of the bifurcationprovided with a substantially [lat surface spaced from the pulley wheelend of said bifurcated sup port adapted to contact with an external bodv to prevent chafing, said support at its upper part providing isterswith the hole in a curved groove which regsaid hollow shaft to providean unbroken surface serving as a cable thimble.

In testimony whereof I affix my signature. STEPHEN R. WARREN.
